Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run. PHYSICAL REVIEW LETTERS 2022; 129:061104. [PMID: 36018635 DOI: 10.1103/physrevlett.129.061104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 03/18/2022] [Accepted: 06/07/2022] [Indexed: 06/15/2023]
Abstract
We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2 M_{⊙} and 1.0 M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14 yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200] Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2 M_{⊙}<m_{PBH}<1.0 M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1 M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
This article has been retracted:
please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at
the request of the authors. The abstract was presented as a
poster in the IMED last year. Our study was about the
association of Ivermectin with reduction in mortality in COVID, a
retrospective study with many limitations (which is innate in these types
of studies). As in any retrospective study, we could not control for all
the confounding variables, mainly severity of disease in patients treated
with either ivermectin or remdesivir. Another important caveat is that it
was conducted in July 2021, eight months ago, when we did not have all
the clinical evidence we have right now about ivermectin in COVID-19. We
were very clear in the abstract conclusions that our results are only
showing an “association”, they are not definitive, and further randomized
clinical trials must be done to prove the efficacy of
Ivermectin. However, the study has been
misinterpreted by a significant number of people in the scientific
community and the general population, stating that based on our study,
ivermectin is effective to reduce COVID-19 mortality. We are really
concerned about this problem because the patients may start taking or
demanding this medication from their physicians, which can potentially be
harmful. We know that a retrospective study like ours cannot be used to
change or guide clinical practice. Retrospective studies are only helpful
to formulate hypothesis that can be utilized to design clinical
trials. This misrepresentation of the
study may lead to a huge public health problem, since Ivermectin is a
medication that is not FDA approved for COVID treatment, and currently
has proven to be ineffective in clinical trials, which are truly the gold
standard to evaluate the efficacy of a medication.

Abstract
BackgroundANCA-associated vasculitides (AAV) are rare in childhood and characterized by necrotizing inflammation in small to medium sized vessels. Most of the available literature in children focuses on clinical subtypes Granulomatosis with Polyangiitis (GPA), Microscopic Polyangiitis (MPA), and Eosinophilic Granulomatosis with Polyangiitis (EGPA). Adult studies have demonstrated differences in clinical outcomes based on myeloperoxidase (MPO) and proteinase 3 (PR3) ANCA specificity (1). There is limited information about the characteristics of MPO- AAV and PR3-AAV in children.ObjectivesThe objective of this study was to review the characteristics of MPO-AAV and PR3-AAV at a children’s hospital in multi-ethnic Central California, United States.MethodsWe performed a retrospective case review of patients less than 18 years of age diagnosed with AAV at a tertiary care children’s hospital in Central California in United States from January 1, 2010 to March 31, 2021. Cases were identified from electronic health records using ICD-9 and ICD-10 codes for vasculitis. Records were reviewed for a diagnosis of AAV based on ACR/EULAR classification criteria. Demographic and clinical data including laboratory parameters including ANCA specificity, treatment, and outcomes were collected. Continuous data were expressed as a median and interquartile range, categorical data as frequency and percentages. Chi-square and Mann-Whitney U tests were used for statistical comparison as appropriate.ResultsEighteen cases of pediatric AAV were identified, of which 10 (55.5%) patients had MPO-AAV and 8 (44.4%) had PR3-AAV. All patients who were MPO positive were diagnosed with MPA. Among PR3-AAV cohort, 7 patients were diagnosed with GPA and 1 patient received diagnosis of MPA. The median age at diagnosis was 12.6 years (IQR 10.1-15.4) in patients with MPO-AAV and 14.8 years (13.8-16.7) in children with PR3-AAV. In MPO-AAV cohort, 90% (n=9) were female, meanwhile 37.5% (n= 3) of patients diagnosed with PR3-AAV were female (p=0.02). Significantly higher proportion of patients diagnosed with MPO-AAV were from racial and ethnic minority groups (n=10, 100%) which included Hispanic (8), Asian (1) and other (1). In comparison, patients with PR3-AAV were predominantly white (n= 7, 87.5%; p <0.01). Median length of hospital stay was 19 days (IQR=12.8-41) in patients with MPO-AAV and 14 days (IQR=9.5-21.8) in patients with PR3-AAV. Rate of ICU admission was 60% in MPO-AAV cohort and 37.5% in PR-3 cohort, although this was not statistically significant. 50% (n=5) of patients in MPO-AAV cohort required dialysis and 25% (n=2) in PR3-AAV cohort. Peak creatinine was higher in MPO-AAV cohort (7.4, IQR 1-13.4 versus 2, IQR 0.7-3.7 mg/dL), although it did not reach statistical significance (p=0.1). PR3-AAV group had significantly higher levels of C-reactive protein (22.9, IQR=7.05-26.3) compared to MPO-AAV cohort (2.25, IQR=0.3-6.2; P=0.02). ENT involvement was more frequent in PR3-AAV cohort (87.5% versus 10%). All patients received treatment with high dose corticosteroids at diagnosis. Other immunosuppressive therapy included cyclophosphamide (40% in MPO-AAV cohort and 75% in PR-3 AAV cohort), rituximab (40% MPO-AAV cohort and 0% in PR-3 AAV cohort), cyclophosphamide and rituximab (10% in MPO-AAV cohort and 25% in PR-3 AAV cohort). Two deaths were reported in MPO-AAV cohort, related to Aspergillus pneumonia and pulmonary hemorrhage.ConclusionOur study reviews characteristics of pediatric MPO-AAV and PR3-AAV in the Central California of United States. We observed a more frequent diagnosis of MPO-AAV in racial/ethnic minority children. Limitations of our study include small sample size. This study highlights the need for further research to understand the impact of ethnicity and MPO and PR3 positivity on pediatric AAV presentation, disease activity and outcomes.References[1]Hilhorst, Marc et al.

Abstract
Work-life balance (WLB) is a subject of primary concern for every organization. This paper attempted to delineate the influence of group travel on the WLB of millennials working in the IT companies in Pune. The study of group travel was compared to individual journeys. Four factors of group travel: escapism, refreshment, bonding, gain a new perspective; we’re used to establish a relationship between group travel and work-life balance. Data were collected from 214 millennials employed in IT companies in Pune using an online survey. Multiple regressions analysis has affirmed that group travel has a positive and significant influence on the work-life balance of the millennials. The findings of this study would contribute to crucial contributors such as the company to modify the policies regarding travel vacation for the employees and acts as marketing inputs to outside stakeholders like travel agencies, hotels, and hospitality businesses.

Abstract
Introduction: The pandemic of Coronavirus Disease 2019 (COVID19) had a significant impact on obstetric surgeries. Obstetric surgical procedures during the COVID-19 pandemic affect individuals who are suspected or proven to be high-risk endeavors. Aim: To evaluate the demographic characteristics, indications, intraoperative and postoperative complications, and foetomaternal outcomes in the women who had an Emergency Peripartum Hysterectomy (EPH) during the first and second waves of the COVID-19 at a tertiary care centre in North India. Materials and Methods: This was a retrospective cohort study, conducted in the Department of Obstetrics and Gynaecology at a tertiary care centre in Uttar Pradesh, India, including women who underwent EPH operated from March 2020 to May 2021 in terms of demographic characteristics, indications, intraoperative and postoperative complications, and foetomaternal outcomes. Information about their self-reported health issues due to traumatic birth (when they came for a follow-up visit at five weeks) were also obtained. Simple frequency, percentage, and proportion were calculated using descriptive statistics. Results: A total number of 1827 deliveries were conducted and out them 11 cases underwent emergency peripartum hysterectomy at our institute during the time frame of the COVID-19 pandemic. All of the patients were in their 20s or 30s, with ages ranging from 21 to 34. All of these were unplanned pregnancies and arrived at various gestational ages. Eight cases had the previous scarring on the uterus, with six women having morbidly adhered placenta. All of the women in the study cohort were unbooked, and 72.73 % (eight out of 11) of them were referred to our centre because they had high-risk factors. Due to substantial blood loss, five females required Critical Care Unit (CCU) support. The study sample had a poor newborn outcome, with three early neonatal deaths out of 11 deliveries. As a part of their 5th-week followup, after the women had been stabilized and discharged from the ICU, they were asked to share their major issues related to health, psychological status and social interaction. The main worries revolved around the newborn child's and COVID-19 positive husband’s health. Pregnant women who delivered during the COVID-19 pandemic had a significant rate of postpartum depression and Post-traumatic Stress Disorder (PTSD). Conclusion: The predominant cause of EPH in the study population was a morbidly adherent placenta. It is critical to protect women's physical and psychological health during traumatic childbirth in order to mitigate the pandemic's alreadyexisting harmful impacts.

Abstract
BACKGROUND Mediastinal lesions are one of the most common lesions of the chest in children and adults. Multidetector computed tomography (MDCT) is the most common investigation done in patients with suspected abnormalities on X-ray. Crosssectional imaging visualises complex anatomy, helps in predicting the tissue of origin, characterises lesions and depicts the extent of involvement of adjacent structures. Complications of mediastinal lesions and emergent conditions, for example, sealed pneumo-mediastinum, tracheoesophageal / pulmonary fistula, a peri-lesional abscess can be well assessed on CECT. The possibility of the lesion as benign or malignant and can be well predicted. Vascular lesions like aneurysms, dissections, and embolism can be evaluated and stable lesions requiring to follow up and unstable lesions requiring emergent treatment are differentiated using MDCT. The objectives of the study were to characterize and identify features pathognomic of specific mediastinal masses on computed tomography and find out diagnostic accuracy of MDCT in mediastinal masses and compare them with pathological results wherever possible. METHODS A prospective study was done in the Department of Radiodiagnosis, Rohilkhand Medical College and hospital, Bareilly for a span of 1 year from November 2018 to October 2019. Our study included 51 patients. Mediastinal lesions were assessed based on size, compartmental localisation, and attenuation and enhancement patterns. RESULTS In our study with 51 patients, 16 lesions were non-neoplastic and 35 were neoplastic lesions. Anterior mediastinal lesions constituted maximum lesions followed by middle and posterior mediastinal lesions. Lymph nodal masses were the commonest lesions out of which 4 cases were tubercular in origin, 4 were lymphomatous and 4 were metastatic. Neurogenic tumours were most common in the posterior mediastinum consisting of 6 cases. 2 vascular lesions were seen, 1 of aortic aneurysm and 1 aortic dissection. The diagnostic accuracy of MDCT was 93 % compared to histopathological results. Computed tomography (CT) plays a major role in evaluating mediastinal masses by virtue of its excellent multiplanar reconstruction capabilities and demonstration of exact anatomic relationships. However, in many situations, histopathological examination is needed to know the exact tissue of origin and for further management. CONCLUSIONS We conclude that CT has a major role in evaluating mediastinal masses regarding location, extent and tissue characterization. It can display certain features pathognomic for particular masses thus obviates the need for invasive procedures. KEY WORDS Mediastinal Lesions, MDCT, Imaging Modality, Histopathology

Abstract
PURPOSE To predict if developing human embryos are permissive to multiple coronaviruses. METHOD We analyzed publicly available single-cell RNA-seq datasets of human embryos for the known canonical and non-canonical receptors and spike protein cleavage enzymes for multiple coronaviruses like SARS-CoV, SARS-CoV-2, MERS-CoV, hCoV-229E, and hCoV-NL63. We also analyzed the expression of host genes involved in viral replication, host proteins involved in viral endosomal sorting complexes required for transport (ESCRT), genes of host proteins that physically interact with proteins of SARS-CoV-2, and the host genes essential for coronavirus infectivity. RESULTS Of the known receptors of SARS viruses, ACE2, BSG, GOLGA7, and ZDHHC5 were expressed in different proportions in the zygote, 4-cell, 8-cell, morula, and blastocysts including the trophectoderm. The MERS-CoV receptor, DPP4, and hCoV-229E receptor, ANPEP, were expressed mainly from the compact morula to the blastocyst stages. Transcripts of the MERS-CoV alternate receptor LGALS1 were detected in most cells at all stages of development. TMPRSS2 transcripts were detected in the epiblast, primitive endoderm, and trophectoderm, while transcripts of the endosomal proteases CTSL, CTSB, and FURIN were expressed in most cells at all stages of development. ACE2 and TMPRSS2 were co-expressed in a proportion of epiblast and trophectoderm cells. The embryonic cells expressed genes involved in ESCRT, viral replication, SARS-CoV-2 interactions, and coronavirus infectivity. The ACE2 and TMPRSS2 co-expressing cells were enriched in genes associated with lipid metabolism, lysosome, peroxisome, and oxidative phosphorylation pathways. CONCLUSION Preimplantation and implantation stage human embryos could be permissive to multiple hCoVs.

Abstract
The ACT-America project is a NASA Earth Venture Suborbital-2 mission designed to study the transport and fluxes of greenhouse gases. The open and freely available ACT-America data sets provide airborne in situ measurements of atmospheric carbon dioxide, methane, trace gases, aerosols, clouds, and meteorological properties, airborne remote sensing measurements of aerosol backscatter, atmospheric boundary layer height and columnar content of atmospheric carbon dioxide, tower-based measurements, and modeled atmospheric mole fractions and regional carbon fluxes of greenhouse gases over the Central and Eastern United States. We conducted 121 research flights during five campaigns in four seasons during 2016-2019 over three regions of the US (Mid-Atlantic, Midwest and South) using two NASA research aircraft (B-200 and C-130). We performed three flight patterns (fair weather, frontal crossings, and OCO-2 underflights) and collected more than 1,140 h of airborne measurements via level-leg flights in the atmospheric boundary layer, lower, and upper free troposphere and vertical profiles spanning these altitudes. We also merged various airborne in situ measurements onto a common standard sampling interval, which brings coherence to the data, creates geolocated data products, and makes it much easier for the users to perform holistic analysis of the ACT-America data products. Here, we report on detailed information of data sets collected, the workflow for data sets including storage and processing of the quality controlled and quality assured harmonized observations, and their archival and formatting for users. Finally, we provide some important information on the dissemination of data products including metadata and highlights of applications of ACT-America data sets.

Abstract
A new gene Rph28 conferring resistance to barley leaf rust was discovered and fine-mapped on chromosome 5H from wild barley. Leaf rust is a highly destructive disease of barley caused by the fungal pathogen Puccinia hordei. Genetic resistance is considered to be the most effective, economical and eco-friendly approach to minimize losses caused by this disease. A study was undertaken to characterize and fine map a seedling resistance gene identified in a Hordeum vulgare ssp. spontaneum-derived barley line, HEB-04-101, that is broadly effective against a diverse set of Australian P. hordei pathotypes. Genetic analysis of an F3 population derived from a cross between HEB-04-101 and the H. vulgare cultivar Flagship (seedling susceptible) confirmed the presence of a single dominant gene for resistance in HEB-04-101. Selective genotyping was performed on representative plants from non-segregating homozygous resistant and homozygous susceptible F3 families using the targeted genotyping-by-sequencing (tGBS) assay. Putatively linked SNP markers with complete fixation were identified on the long arm of chromosome 5H spanning a physical interval between 622 and 669 Mb based on the 2017 Morex barley reference genome assembly. Several CAPS (cleaved amplified polymorphic sequences) markers were designed from the pseudomolecule sequence of the Morex assembly (v1.0 and v2.0), and 16 polymorphic markers were able to delineate the RphHEB locus to a 0.05 cM genetic interval spanning 98.6 kb. Based on its effectiveness and wild origin, RphHEB is distinct from all other designated Rph genes located on chromosome 5H and therefore the new locus symbol Rph28 is recommended for RphHEB in accordance with the rules and cataloguing system of barley gene nomenclature.

Abstract
Rabindra Sarovar lake is an artificial freshwater lake in the arsenic infested eastern region of India. In this study, using the genome resolved metagenomics approach; we have deciphered the taxonomic diversity as well as the functional insights of the gene pools specific to this region. Initially, a total of 113 Metagenome Assembled Genomes (MAGs) were recovered from the two predominant seasons, that is, rainy (n = 50) and winter (n = 63). After bin refinement and de-replication, 27 MAGs (18 from Winter season and 9 from Rainy season) were reconstructed. These MAGs were either of high-quality (n = 10) or of medium quality (n = 17) that was determined based on genome completeness and contamination. These 27 MAGs spanning across 6 bacterial phyla and the most predominant ones were Proteobacteria, Bacteroidetes, and Cyanobacteria regardless of the season. Functional annotation across the MAGs suggested the existence of all known types of arsenic resistance and metabolism genes. Besides, important secondary metabolites such as zoocin_A, prochlorosin, and microcin were also abundantly present in these genomes. The metagenomic study of this lake provides the first insights into the microbiome composition and functional classification of the gene pools in two predominant seasons. The presence of arsenic metabolism and resistance genes in the recovered genomes is a sign of adaptation of the microbes to the arsenic contamination in this region. The presence of secondary metabolite genes in the lake microbiome has several implications including the potential use of these for the pharmaceutical industry.

Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run. PHYSICAL REVIEW LETTERS 2021; 126:241102. [PMID: 34213926 DOI: 10.1103/physrevd.97.102002] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 03/31/2021] [Accepted: 05/23/2021] [Indexed: 05/21/2023]
Abstract
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Abstract
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Singh D, Montoure J, Ketterson ED. Exposure to artificial light at night accelerates but does not override latitude-dependent seasonal reproductive response in a North American songbird. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2021; 279:116867. [PMID: 33770652 DOI: 10.1016/j.envpol.2021.116867] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 02/23/2021] [Accepted: 02/28/2021] [Indexed: 06/12/2023]
Abstract
In the modern era of industrialization, illuminated nights have become a common defining feature of human-occupied environments, particularly cities. Artificial light at night (ALAN) imposes several known negative impacts on the neuroendocrine system, metabolism, and seasonal reproduction of species living in the wild. However, we know little about the impact of ALAN on populations of birds that either live year-round in the same location or move to different latitudes across seasons. To test whether ALAN has a differing impact on the reproductive timing of bird populations that winter in sympatry but breed at different latitudes, we monitored sedentary and migratory male dark-eyed juncos that were or were not exposed to low intensity (∼2.5 ± 0.5 lux) ALAN. All groups were held in common conditions and day length was gradually increased to mimic natural day length changes (NDL). We assessed seasonal reproductive response from initiation to termination of the breeding cycle. As expected based on earlier research, the sedentary birds exhibited earlier gonadal recrudescence and terminated breeding later than the migratory birds. In addition, resident and migrant birds exposed to ALAN initiated gonadal recrudescence earlier and terminated reproductive events sooner as compared to their conspecifics experiencing NDL. Importantly, the difference in the reproductive timing of sedentary and migratory populations was maintained even when exposed to ALAN. This variation in the seasonal reproductive timing may likely have a genetic basis or be the result of early developmental effects imposed due to different light regimes related to the latitude of origin. This study reveals first that ALAN accelerated reproductive development across both migrants and residents and second that latitude-dependent variation in reproductive timing is maintained despite exposure to ALAN. These results corroborate a relationship between latitude, population, and reproductive timing while also revealing ALAN's impact on seasonal reproductive timing. This study reveals that, ALAN accelerated reproductive development but maintained latitude-dependent variation in reproductive timing across both migrant and resident bird populations.

Abstract
An organophosphorus pesticide malathion biodegradation was investigated by using the bacteria Ochrobactrum sp. M1D isolated from a soil sample of peach orchards in Palampur, District Kangra, Himachal Pradesh (India). The bacterium was able to utilize malathion as the sole source of carbon and energy. The isolated bacterium was found psychrotolerant and could degrade 100% of 100 mg l-1 malathion in minimal salt medium at 20°C, pH 7·0 within 12 days with no major significant metabolites left at the end of the study. Through GCMS analysis, methyl phosphate, diethyl maleate, and diethyl 2-mercaptosuccinate were detected and identified as the major pathway metabolites. Based on the GCMS profile, three probable degradation pathways were interpreted. The present study is the first report of malathion biodegradation at both the psychrophilic and mesophilic conditions by any psychrotolerant strain and also through multiple degradation pathways. In the future, the strain can be explored to bio-remediate the malathion contaminated soil in the cold climatic region and to utilize the enzymatic systems for advanced biotechnology applications.

Abstract
The development and spread of resistance to antimicrobial drugs is hampering the management of microbial infectious and wound healing processes. Curcumin is the most active and effective constituent of Curcuma longa L., also known as turmeric, and has a very long and strong history of medicinal value for human health and skincare. Curcumin has been proposed as strong antimicrobial potentialities and many attempts have been made to determine its ability to conjointly control bacterial growth and promote wound healing. However, low aqueous solubility, poor tissue absorption and short plasma half-life due its rapid metabolism needs to be solved for made curcumin formulations as suitable treatment for wound healing. New curcumin nanoformulations have been designed to solve the low bioavailability problem of curcumin. Thus, in the present review, the therapeutic applications of curcumin nanoformulations for antimicrobial and wound healing purposes is described.

Abstract
BACKGROUND: Cardiovascular disease is one of the main causes of mortality in patients with chronic obstructive pulmonary disease (COPD), and atherosclerosis is a cause of cardiac comorbidities in COPD. However, it is not clear whether airflow limitation is associated with atherosclerosis irrespective of smoking.OBJECTIVE: To investigate whether airflow limitation is independently associated with vascular stiffness.METHODS: We enrolled 18 893 participants (male 70.5%; mean age 47.5 ± 9.8 years; never smokers 44.2%) who underwent spirometry and brachial-ankle pulse wave velocity (baPWV) as part of a standard health examination at Ajou University Hospital, Suwon, South Korea, from January 2010 to December 2015.We defined vascular peripheral atherosclerosis as baPWV ≥ 1400 cm/s and airflow limitation as pre-bronchodilator ratio of forced expiratory volume in 1 sec (FEV1) to forced vital capacity (FVC) <70%.RESULTS: Mean baPWV was higher in subjects with airflow limitation (1477.6 ± 331.7 cm/sec, n = 638) than in those without airflow limitation (1344.1 ± 231.8 cm/sec, n = 18255, P < 0.001). In multivariate logistic regression analysis, the following were independent predictors associated with peripheral atherosclerosis (P < 0.05): age, male sex, fasting serum glucose, mean blood pressure, serum leukocyte count, serum low density lipoprotein level and FEV1.CONCLUSION: Airflow limitation was an independent predictor of vascular stiffness irrespective of smoking history, which suggests that airflow limitation is linked with atherosclerosis.

Abstract
Improving resistance to barley leaf rust (caused by Puccinia hordei) is an important breeding objective in most barley growing regions worldwide. The development and subsequent utilization of high-throughput PCR-based codominant molecular markers remains an effective approach to select genotypes with multiple effective resistance genes, permitting efficient gene deployment and stewardship. The genes Rph20 and Rph24 confer widely effective adult plant resistance (APR) to leaf rust, are common in European and Australian barley germplasm (often in combination), and act interactively to confer high levels of resistance. Here we report on the development and validation of codominant insertion-deletion (indel) based PCR markers that are highly predictive for the resistance alleles Rph20.ai and Rph24.an (both referred to as Rph20 and Rph24).
